list NFC targets


nfc-list [ options ]


nfc-list is a utility for listing any available tags like ISO14443-A, FeliCa, Jewel or ISO14443-B (according to the device capabilities). It may detect several tags at once thanks to a mechanism called anti-collision but all types of tags don't support anti-collision and there is some physical limitation of the number of tags the reader can discover.

This tool displays all available information at selection time.



Tells nfc-list to be verbose and display detailed information about the targets shown. This includes SAK decoding and fingerprinting is available.

-t X

Polls only for types according to bitfield value of X:

  1: ISO14443A
  2: Felica (212 kbps)
  4: Felica (424 kbps)
  8: ISO14443B
 16: ISO14443B'
 32: ISO14443B-2 ST SRx
 64: ISO14443B-2 ASK CTx
128: ISO14443B iClass
256: ISO14443A-3 Jewel
512: ISO14443A-2 NFC Barcode

So 1023 (default) polls for all types. Note that if 16, 32, 64 or 128 then 8 is selected too.


For an ISO/IEC 14443-A tag (i.e.Mifare DESFire):

      UID (NFCID1): 04  45  35  01  db  24  80
